SM Beads are controlled for impedance limits only. Minimum impedance values are specified for the + marked frequencies. The

minimum impedance is typically the listed value less 20%. SM Beads in 73, 43 and 44 materials are measured for impedance on

the 4193 Vector Impedance Analyzer. The 52 and 61 SM Beads are tested for impedance on the 4291A RF Impedance Analyzer.

The maximum practical current rating for these SM Beads is 5 amps, check the component bias curves. The 019/021/037

and 044 SM Beads can withstand a continuous current of 10 amps resulting in a component temperature rise < 40 °C
